For those wanting to add page numbers to existing PDFs, Smile has released new versions of PDFpen and PDFpenPro, their PDF manipulation software. Version 5.5 adds the capability to put page numbers in either the header or the footer of the page, and the page numbers can start on any page. Visually, page numbers can be aligned left, right, or center, or even inside or outside for facing pages, and they can be formatted as Roman numerals, letters, or Bates Numbering. Also new in this update is initial support for full-screen mode in Mac OS X 10.7 Lion, along with some unspecified bug fixes. ($59.95/$99.95 new, free update, 41.5 MB)
Thoughtful, detailed coverage of the Mac, iPhone, and iPad, plus the TidBITS Content Network for Apple consultants.
